LED screen cover with transparent circular holes formed by multilayer periodical change black nets

Abstract

The invention belongs to the field of LED display, and in particular relates to an LED screen cover with transparent round holes formed by multi-layer periodically changing black nets. A kind of LED screen cover with transparent circular holes formed by multi-layer periodically changing black nets. The black mesh forms round holes distributed in a dot matrix. There is no black mesh in the round holes, which maintains the transparency of the screen body and is a light-transmitting round hole. The beneficial effect of the present invention is that the shield body reduces the luminous intensity of the pixel unit; and the light transmission in part of the light-transmitting area restrains the mutual crosstalk between pixels, and the part of the light-transmitting area emits light, reducing the periodicity existing in the prior art The black area network structure, strong graininess, glaring local light intensity, and technical shortcomings that are not suitable for close viewing. The beneficial effect is that the PC plastic paper can be hot-compressed or printed or spray-painted, which can satisfy large-scale display on a large screen, has good display effect, low cost, simple technology, and scrub resistance.

Description

technical field [0001] The invention belongs to the field of LED display, and in particular relates to an LED screen cover with transparent round holes formed by multi-layer periodically changing black nets. Background technique [0002] As we all know, the main parameter of the LED screen is the pixel. The smaller the pixel, the higher the resolution of the LED screen and the better the displayed image. The distance between pixels, such as P5, means that the periodic interval between pixels is 5mm, also known as the pixel period, represented by a. Pixel cycle explanation: starting from any pixel in the middle of the large screen, every time a pixel cycle a passes in the vertical and horizontal directions, that is, every time a=5mm passes, there is another pixel. The diameter of the pixel barrel is b=2.5 mm and the height h=0.5 mm. Each full-color pixel includes three color elements of red, green, and blue, such as 2R2G1B. There is a 5mm black area between pixels. The pi...

Problems solved by technology

This technical defect specifically includes periodic black area network structure, strong graininess, glaring local light intensity, too dark dark gaps, and too much contrast between light and dark, so it cannot be viewed at close range.
